1. Batteries of different capacity, type, and brand should not be used together. The
manufacturer has approved only the type, capacity, and brand of battery originally shipped
with the UPS. Please consult the UPS manufacturer before replacing batteries with any
batteries not meeting these specifications.
2. When cleaning the outside of the UPS use only a soft cloth and clear water. Do not use oily
substances, solvents, or abrasive cleaners, etc.
3. The UPS should be kept away from ignition sources as well as all electrical equipment that
may cause sparks.
4. Be careful not to store flammable, explosive, or corrosive substances in the same area as
the UPS or any add-on battery cabinets.
5. If the UPS is routinely disconnected for long periods, be sure to regularly connect the UPS
and charge the battery to prevent battery damage as the result of self-discharging.
4.5 Frequent Trouble Causes
If the UPS fails to work properly after installation and start-up, please don't automatically
assume that a UPS failure has occurred. Please refer to the following steps to try to identify a
possible cause.
Problem 1
Main supply and output are normal after start-up but the alarm buzzer is sounding
intermittently.
Possible cause: Unstable AC power input as a result of poor input connections at a breaker,
wall receptacle, or UPS terminal block.
Solution: Check all input power connections.
Problem 2
After UPS is started, the output voltage is normal, but the UPS is in bypass mode (BYPASS
light illuminated).
Possible cause: Too much load is connected to the UPS.
Solution: Remove or turn off connected loads in increments until the BYPASS light is
extinguished. If UPS is overloaded, it may be necessary to install an additional UPS or one with
a higher capacity rating.
As long as the UPS is connected to a live power source and the UPS
input circuit breaker and battery circuit breaker is turned on, the UPS
battery will be kept in a charged state.
(Note: Some bypass operations are caused as a result of starting up
high inrush loads. In such cases, bypass operation will be
temporary, and the UPS will return to normal operation as soon as
load inrush current subsides.)
